extension of access
Last reviewed 01/2018
If adequate access to the appendix cannot be obtained with the initial incision, extension can be undertaken. For example, a retrocaecal appendix may be difficult to retrieve with a standard Lanz incision. It may require a lateral extension of the deep incision into the abdominal wall muscles. Conversely, a medially sited or pelvic appendix may be more advantageously reached with division of the rectus sheath and medial retraction of rectus abdominis.
